Mike, excellent question. He has a decent copy of "Green Street" by Grant Green on Blue Note. A good recording on decent vinyl....several scratches but nothing out of the ordinary. I have the Hoffman/Gray Acoustech remastered reissue from Blue note on 200g vinyl 45 rpm. I ripped my copy to my computer using DSD and then ripped it down to multiple sample rates to see if I could hear a material difference. I enlisted his ears to assist me....not really a blind test but he didnt know which version was playing. He was astounded at every sample rate and asked me to give him the files. We then discussed the slippery slope. We jointly surmised that to follow the letter of the law, he would need to "borrow" my album and its "digital archive" for evaluation in his system.
Now i have no intention of distributing digital copies of my music to anyone but i dont see anything wrong with loaning them mine or assisting them by recording their album. In this case what really caused me to pause, and a key fact that i intentionally did not mention initially in this posting, was that I would believe my remastered Grant Green album to be a "different" recording than what he has. It just started me thinking and i thought i would pose the question to the audiophile community and get some broad, generic input. Regards
